    6400 starter removal

    I have a 6400 with loader, solenoid clicks when I try to start. Can jump across terminals then will start off key a few times, then back to clicking at solenoid. Bought two new solenoids none fit, and cant figure out how they come off, without removing starter. Is there a relay between solenoid and key that could be bad, if not, how does solenoid come off. If I have to remove starter, HOW IN THE WORLD DO I GET THE BOTTOM STARTER BOLT OFF AND BACK ON. Tried today, used crow foot wrenches, every sort of swivel and extension known to man, no luck, I can barely move it with swivel, but access from bottom is horrible. Wondering if there is an easier way to access or if someone has had any success on these before, scared to start without more information. hoping it is a relay, however starter drive does act funny. thanks for any help.

    Attached are pictures from JDparts. The starter picture might help show how the solinoid comes off. Also a picture of a starter relay. It mounts to the starter. If you do not have one it may help. Solinoid is part number AL117012 it repalces part number AL113664

    This information is correct. The relay should be bolted right on the end of the starter. The solenoid is held on with three screws #8 in the diagram. I don't think you can get out all three of them without removing the starter. There is a special wrench made to remove the lower bolt. Part number is KJD10213. The wrench looks like a cut off box end wrench welded onto a long bolt. Even with the special wrench, getting the starter off is a real bear.

    Question Starter Wrench

    I am sure this same wrench will work for the starter of my JD 6415. Is this available from John Deere? KD tools?

    I don't need one yet (knock on wood)

    Wrench size and length of bolt? If I were to make one.

    Thanks

    Checking JDparts I will NOT need this special wrench! My JD 6415 has metric Hex Socket Head Screws holding the starter on that use an 8mm hex wrench. So the special wrench will not work.

    JD 6400 uses a 3/8" stud with a hex nut that takes a 9/16" wrench
    JD 6410 uses a 10mm stud with a flanged hex nut that takes a 15mm wrench
    JD 6415 & JD6420 uses a M10 Hex Socket Head Screw that takes a 8mm hex wrench

    There are definitely two different wrenches for 9/16" and 15mm sizes. They are available through John Deere. The bolt section is about 8 inches long although I think 9 or 10 inches would work better. I wasn't aware they started using allen head bolts on the 15 and 20 series. I'll have to check and see if there is a special allen wrench for the job.

    Thank you for taking the time to reply, the diagrams are very helpful, and right on the money. Worked on it today, discovered the solenoid would engage starter when jumped, so checked other problems, zeroing in on the front starter relay, it clicked off the switch, and engaged the starter when shorted. Replaced it, and for the time being fixed my problem. Dont really understand how it works, but none the less it does. thanks again, good luck.

    Really appreciate the tip on the wrench, for now dont have to remove it, but will buy or make one for the inevitable, Just to help others, if you remove the front starter relay, and mash the two bundles of wires down, it seems to make the bottom bolt more accessible with the wrench you described,,, A GREAT TIP FOR THIS PROJECT. thanks again and hope you dont have to remove one.
